0–100, higher is better. How it is calculated

DCellar is a technology startup providing a decentralized storage console aimed at developers working with the BNB Greenfield decentralized storage blockchain and BNB Smart Chain. The website targets blockchain developers and offers tools to facilitate integration and usage of decentralized storage solutions. The company is relatively new, founded in 2023, and uses privacy protection for domain registration, which is common for startups in this sector. The website is built on modern web technologies including Next.js and WebAssembly, hosted likely on AWS infrastructure. It employs Google Analytics for user tracking but lacks visible privacy and cookie policies, which is a compliance gap. Security posture is moderate with HTTPS enforced and some security headers present, but DNSSEC is not enabled and additional headers could improve security. No contact information or incident response details are provided, limiting transparency. Overall, the site is professional and functional but would benefit from enhanced privacy compliance and security practices.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

3 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The business operates in the blockchain technology sector, focusing on decentralized storage solutions for developers. Its market positioning is niche, targeting blockchain developers who require storage tools compatible with BNB Greenfield and BNB Smart Chain. The business model appears to be service-oriented, providing developer tools and storage consoles. The company leverages partnerships or integrations with domains like bnbchain.org and nodereal.io, indicating ecosystem collaboration. Growth indicators include recent domain registration and use of modern technologies. However, lack of public contact details and privacy policies may hinder trust and wider adoption. The company is small-sized and based in Great Britain, with no parent or subsidiary companies identified.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is properly implemented, and a Content Security Policy is present to upgrade insecure requests. However, DNSSEC is not enabled, which is a missed opportunity to secure DNS queries. Security headers are minimal, lacking HSTS, X-Frame-Options, and other common protections. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of privacy and cookie policies, as well as incident response contacts, indicates gaps in compliance and readiness. The use of Google Analytics without consent mechanisms raises privacy concerns. Overall, the security posture is adequate for a startup but requires improvements to meet best practices and regulatory compliance.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement comprehensive privacy and cookie policies with explicit user consent mechanisms to comply with GDPR and other regulations.
  3. Add clear contact information including support and security incident response channels to improve transparency and trust.
  4. Enhance security headers by adding HSTS, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  5. Conduct regular security audits and vulnerability assessments to identify and mitigate potential risks.

Technical notes

Notes

The website is built using Next.js, a modern React framework, and incorporates WebAssembly modules compiled with TinyGo, indicating advanced technical implementation. Hosting appears to be on AWS infrastructure, as suggested by the registrar and DNS servers. Performance is moderate with prefetching and preconnecting to multiple external resources. Mobile optimization is good, with responsive design and font loading optimizations. SEO is supported by proper meta tags and Open Graph data. Accessibility features are basic but present. The technical stack is modern and suitable for a developer-focused platform, though some improvements in security headers and privacy compliance are needed to reduce technical debt and enhance robustness.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
